Parker Chomerics CHO-SEAL® Co-Extruded Elastomer Gaskets provide dual performance in one simple design. By a seam vulcanization process, CHO-SEAL® or CHO-SIL® conductive elastomers are extruded in parallel with nonconductive elastomers to provide EMI shielding and corrosion protection from one gasket. The outer, nonconductive gasket acts as an extra environmental seal to keep moisture away from the conductive gasket/flange interface.

This prevents corrosion of the mating flange in marine or airborne environments. Co-extruded gaskets are also cost effective, as they permit the use of existing flange designs and provide for gasket attachment via a less expensive non-conductive elastomer. A similar two gasket shielding system requires a costly double groove flange design.
